# Half Life of Charge on metal ball.

Let a metal ball of Radius $$r$$ is placed in infinite homogeneous conducting medium having dielectric constant $$k$$ , resistivity $$\rho$$ . Let at time t=0 , Q charge is given to ball , then find the half Life of the charge present on sphere.

###### It is simple version of that problem.

Yes Answer is independent of Size of ball...
